Bare butt nap

I just went in to Trevor's room to get him up from his nap. And I found a sleeping little boy with his pant around him knees and no diaper on and with his bare butt in the air. I checked to see if her had peed in the bed but it wasn't wet. And his diaper that was on the floor was dry also. I guess he must of needed to air out. I wanted to take a picture but he woke up before I could get to the camera. Right now we his running around the house with his diaper on but his pants are around his ankles. Goofy Boy!!!
